STM32F767ZI 与 OV5640 的代码？

jiapei100

Hi, all:

求助！！

只有一块 STM32F767ZI 的板子，想驱动ATK-OV5640，但是搜索全网，没有找到相关资料。
Openedv 只有相关STM32F429驱动ATK-OV5640的例子：http://www.openedv.com/thread-77924-1-1.html

有现存的代码可以参照一下吗？谢谢...

1）硬件：我不是买的阿波罗STM32F767ZI，而是买的 Nucleo-F767ZI 。
ATK-OV5640怎么接 Nucleo-F767ZI ？

        9,ALIENTEK OV5640摄像头模块,连接关系为:  
                OV5640模块 ------------ STM32开发板
                 OV_D0~D7  ------------  PB8/PB9/PD3/PC11/PC9/PC8/PC7/PC6
                 OV_SCL    ------------  PB4
                 OV_SDA    ------------  PB3
                 OV_VSYNC  ------------  PB7
                 OV_HREF   ------------  PH7
                 OV_RESET  ------------  PA15
                 OV_PCLK   ------------  PA6
                 OV_PWDN   ------------  PCF8574_P2

2）软件：

编译还是有这两个错误...

有什么配置需要特殊注意的么？

1）硬件：怎么接线？
我不是买的阿波罗STM32F767ZI，而是买的 Nucleo-F767ZI 。ATK-OV5640 怎么接 Nucleo-F767ZI？板子上，没有 PB8/PB9/PD3/PC11/PC9/PC8/PC7/PC6, PB4, PB3, PB7, PH7, PA15, PA6, PCF8574_P2 等这些 pins ？

        9,ALIENTEK OV5640摄像头模块,连接关系为:  
                OV5640模块 ------------ STM32开发板
                 OV_D0~D7  ------------  PB8/PB9/PD3/PC11/PC9/PC8/PC7/PC6

                 OV_PCLK   ------------  PA6
                 OV_PWDN   ------------  PCF8574_P2



2）软件：编译错误！
用你给我的资料，编译仍然存在两个错误：

[mw_shl_code=bash,true]/opt/GCCToolChains/gnu-mcu-eclipse/arm-none-eabi-gcc/7.2.1-1.1-20180401-0515/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/bin/ld: F767ZI_OV5640_Openedv.elf section `.bss' will not fit in region `RAM'

makefile:77: recipe for target 'F767ZI_OV5640_Openedv.elf' failed
make: *** [F767ZI_OV5640_Openedv.elf] Error 1[/mw_shl_code]


我用的是 GNU MCU Eclpse  。


能不能再给一点细节的建议？谢谢...
